Please note that virtuoso is the database backend of nepomuk, and akonadi is a
set of agents for the kdepim resources (one of them is a feeder for nepomuk).
You could probably disable nepomuk indexing if it takes too much cpu for you
or you don't use it.

Eventhough I would not call virtuoso rock solid your mythlogserver seems to be
also segfaulting, maybe you have an issue with the memory hardware and
revealing in intensive applications.
Anyway, nepomuk includes a nepomukcleaner that you can run and check if that
improves things for you.
Thanks,
